Renji and Zabimaru come to the real world following a sword fiend. Zabimaru's two halves, Chimpette and Snakey, split up to search. They find the sword fiend quickly but he escapes. Snakey follows him and is convinced that being free is better. Snakey has trouble doing anything since most people can't see him. Karin is the only person who can see him and ends up taking him home. Renji and Chimpette are waiting in the park and Chimpette is feeling lonely because Snakey isn't there. Ichigo returns home and finds Snakey. After Snakey finds out that Ichigo is a soul reaper he runs away only to encounter the sword fiend. Snakey begins to fight him and almost wins until the sword fiend captures Karin who was following Snakey. Right as Snakey is about to die Chimpette and Renji return to save him and defeat the sword fiend. Ichigo takes Karin home convincing her it was all a dream, even though she knew it wasn't. Having resolved his differences, Snakey, Chimpette, and Renji return to Soul Society.
